I have a list of e-mail addresses for members of my site. Now I want to be able to prevent duplicate instances of the same member but I also don't want to have to do a SELECT each time I add a group of people. Is there something to issue in PERL to check without connecting to MySQL or is there a MySQL technique to be able to do this without so many connections?
